Terminal box
Technical field
The utility model relates to the electric energy meter technical field, specifically is the terminal box on a kind of electric energy meter.
Background technology
The terminal box of prior art comprises body, is located at copper bar and a plurality of terminal contiguous block on the body, and the part of the part of said copper bar, a plurality of terminal contiguous blocks all is embedded in the body.The length direction of the length direction of said copper bar and a plurality of terminal contiguous blocks is parallel to each other.The end of another part of said a plurality of terminal contiguous blocks is equipped with a wire connection hole.Because being the length direction along the terminal contiguous block, extends by the lead that connects through wire connection hole; Therefore a section lead that extends out will inevitably influence the screw retention on the copper bar of bottom; Make the screw on the copper bar be difficult to fixing fast; So not only influence work efficiency, and will inevitably make the length of copper bar increase, thereby improved the cost of terminal box along the length direction extension of terminal contiguous block.
The utility model content
The technical matters that the utility model will solve is, overcomes the defective of above prior art, and a kind of easy for installation and terminal box that cost is low is provided.
The technical scheme of the utility model is, a kind of terminal box is provided, and comprises body, is located at copper bar and a plurality of terminal contiguous block on the body, and the part of the part of said copper bar, a plurality of terminal contiguous blocks all is embedded in the body; The length direction of the length direction of said copper bar and a plurality of terminal contiguous blocks is parallel to each other; Be equipped with a joint pin between terminal contiguous block and copper bar on described a plurality of terminal contiguous block, the center of said joint pin is provided with a wire connection hole.
After adopting above structure, the utility model compared with prior art has the following advantages:
Be equipped with a joint pin between terminal contiguous block and copper bar on a plurality of terminal contiguous blocks of the utility model terminal box; The center of said joint pin is provided with a wire connection hole; Because the lead that this wire connection hole connects is vertical terminals contiguous block and copper bar, therefore reduced the extension on the terminal contiguous block length direction, do not influencing the length that has also reduced copper bar under the fixing prerequisite of copper bar screwing like this; Thereby not only reduced the production cost of terminal box; And, make that the screw on the copper bar is able to fixing fast because lead to extending below, has therefore made things convenient for the screw retention on the copper bar; Thereby not only solved problem easy for installation, and improved production efficiency.
As improvement, described body is provided with the groove of ccontaining a plurality of joint pins, and the further like this length that reduces copper bar provides cost savings.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing; A kind of terminal box of the utility model comprises body 1, is located at copper bar 2 and a plurality of terminal contiguous block 3 on the body 1, and the part of the part of said copper bar 2, a plurality of terminal contiguous blocks 3 all is embedded in the body 1; A part that is copper bar 2 is embedded in the body 1; The other part of copper bar 2 is exposed outside body 1, and the part of a plurality of terminal contiguous blocks 3 is embedded in the body 1, and the other part of a plurality of terminal contiguous blocks 3 is exposed outside body 1; The length direction of the length direction of said copper bar 2 and a plurality of terminal contiguous blocks 3 is parallel to each other, and promptly both are non-intersect for copper bar 2 and a plurality of terminal contiguous block 3; Be equipped with a joint pin 4 between terminal contiguous block 3 and copper bar 2 on described a plurality of terminal contiguous block 3, joint pin 4 is welded on a plurality of terminal contiguous blocks 3, and the center of said joint pin 4 is provided with a wire connection hole 5.
Described body 1 is provided with the groove 6 of ccontaining a plurality of joint pins 5.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
